lconnections at the required rate of speed to effect the spinning or twisting, and the said.

A yarn or thread as fast as it is spun or twisted is wound upon a bobbin or cop-tube mounted upon a suitable spindle or upon the bare blade of the receiving-spindle.

My invention has relation to machines of this general class and it consists in novel and improved features of construction and arrangement which are embodied in and in connection with `a receiving-spindle suitable for use in such machines.

An embodiment of the features of the invention in the best and most complete form which has been devised by me is illustrated in the drawings, in which- Figure 1 is a sectional view of the said embodiment. Fig. 2 is a view in horizontal section on line 2 2, Fig. 1. Fig. 3 is a bottom view of the sleeve and its flange. Fig. 4 shows in side elevation a portion of the sleeve and its flange.

A spindle proper is shown at 1, and at 2 is shown a support therefor, the latter being bored vertically to receive the bushings, which are marked 3 and 4. The'lowerportion of the spindle is itted to the interiors of the said bushings with capacity to turn freely therein, the said bushings constituting bolster-bearings. The lower bushing 3 rests upon a shoulder or surface at or near the bottom ofthe vertical bore of the support 2, and

thereby is supported vertically. It may be held from rotating with the spindle, if desired, by means of a screw or Xed pin 31, projecting inwardly lfrom the vertical shell of the support, the exterior of the bushing?, be-

ing formed with a longitudinal groove 32 to receive said pin and the inner end of the said screw or pin engaging with the'side walls of said groove for the purpose of holdingA the bushing from rotating. I contemplate omitting the locking means for bushing 3 in some cases, especially when working at very high speeds, in order that by permitting the said bushing to rotate with the spindle the action may be rendered easier and the wear may be divided. The upper bushing 4 is secured in place and held from rotating by means of a screw 41, tted to a hole tapped through the vertical shell of the support and taking by its inner end against the said bushing. The lower bushing 3 is reduced in diameter intermediate its upper and lower ends to afford space for oil around saidbushing, and holes 33 33 are made through the intermediate portion of the shell of the bushing to permit access of the oil to the spindle within the bushing and circulation of the oil. The usual reservoir for oil is provided, as at 5, its interior passage communicating with the vertical bore of the support and said reservoir having the usual hinged cap or cover 51.

. The 'spindle 1 is suitably stepped within the support 2. In the present embodiment of the invention the spindle 1 is furnished with an anti-friction-step, its lower end having a plane surface resting upon the edges of two lens-shaped disks 6 6, which latter are mounted side by side upon a pin 61, having its ends mounted in opposite portions of the lower end of bushing 3. Each disk contacts with the bottom end of the spindle at a singlepoint, and as the disks turn freely upon the pin 61 the resistance to the rotation of the spindle that is offered at the step-bearing is reduced to a minimum. The upper portion or blade of the spindle 1 tapers gradually from shortly above the u per end of the support to near the upper en of the spindle.`

The said upper end ofthe spindle is shaped as a cylindrical tip 111, having a pointed eX- tremity. To the spindle above the support;

2 is applied the sleeve 7. The upper end of,y the latter is occupied by a plug 71, in the under side of which is formed a socket receivingv and fitting the tip of the spindle and forming IOO a bearing which coacts with the said tip. The lower portion of the sleeve iits the exterior of the spindle at and adjacent the upper end of the support. The sleeve may receive directly upon its bare exterior the yarn or thread which is being spun or twisted and wound, or a cop-tube or bobbin may be employed, as usual. A bobbin is shown at 74, and the load of yarn upon the latter is indicated at 75. At 72 is shown a bobbin-cup to receive the lower end or head of the bobbin 74, or a suitable cup may be employed to engage with the lower end of a cop-tube. The pull of the yarn or thread which is being spun or twisted as such yarn or thread is carried around by the action of the rotating flier or ring communicates movement of ro` tation to the sleeve. The resistance which is offered to the rotation of the sleeve tends to cause the sleeve to lag behind the flier or ring in speed, and this tendency to a slower speed of the sleeve causes the yarn to become wound upon the exterior of the sleeve or upon the bobbin or other yarn or thread receiver which is applied thereto in the wellknown manner. The sleeve is provided ad# jacent the cup 72 with a projecting iiange,

as 73, for use 1n producing the drag by means of which the retardation of the sleeve in its rotation as it is drawn around by the tension of the yarn or thread being spun or twiste is regulated.

The drag collar is shown at S. It e11- circles the spindle and lower end of sleeve 7 just above the upper end of upper bushing 4 and is mounted upon said end of said bushing. ,An internally-threaded rim or skirt depending from said drag-collar fits over and screws upon the upper end of bushing 4, the said end being enlarged in order that it may constitute a proper support for the drag-collar. The drag-collar is formed with an upwardly-extending rim S3, encircling a chamber 84, in which the flange 73 of the sleeve 7 is received. Between the floor of said chamber and the said flange 73 the drag-washer 85 is placed. The lower end of sleeve 7 projects through the drag-washer and some distancebelow the same,being received in the enlargement 44 of the bore of the upper bushing 4.` The described construction and arrangement of parts protect the drag-washer from access of oil from the bearing-surfaces of the sleeve, spindle, and bushing, and therefore proper and uniform action of the said drag-washer is insured. For the purpose of increasing the frictional hold or engagement between the 'flange 73 and the drag-washer the under surface of said flange may be roughened or grooved radially, as in Fig. 3, if desired. For the purpose of enabling the degree of drag to be varied when required I make provision for raising and lowering the drag-collar relatively to the spindle and the sleeve 7. This provision is made in the present instance by screwing the drag-collar upon the upper end of the upper bushing 1l, as al ready described. By turningT the drag-collar in one direction or the other its position vertically may be varied. Adjustment of the drag-collar upward increases the extent to which the drag-washer is compressed between the drag-collar and the lflange 73 of sleeve 7, and such adjustment may be increased until the entire weight of the sleeve and its load is supported by the said llange resting upon the drag-washer. For the purpose of holding the drag-collar in the desired position after adjustment a suitable locking or latching device is employed in connection therewith. A convenient device for the purpose is illustrated in the drawings. [n the latter the upper surface of the top of the vertical portion or standard of the stationary spindle-support is formed with a circular series of rshallow holes or notches, as at 10. A hole is bored upward into the under side of the drag-collar, near the outer edge thereof, and in said hole is placed a small bolt 101, which is backed up by a spring 102. The spring projects the lower end of the bolt into one of the holes or notches 1() when the rotary movement of the drag-collar brings the bolt opposite such hole or notch, and thereby the drag-collar is held from accidental loss of adjustment. When power is applied by the attendant to the drag-collarsullicient to overcome the tension of the spring, the ybolt gives way sufficiently te enable the drag-collar to be rotated by hand as required.

For the purpose of preventing the sleeve from rising during the operation of doil ing a catch is provided for engagement therewith. This catch consists, preferably, of a pin, as 11, working radially inward through a hole in the upturned rim of the drag-collar and projecting at its inner end above the flange 73 of the sleeve. The said pin is attached to a llat spring, as 11.9, which is attached to the exterior of the drag-collar.

It will be perceived that in the construction which has been described the spindle is free to rotate in unison with the sleeve in consequence of the frictional contact of the sleeve therewith. The sleeve, however, is capable of rotating independently upon the spindle. This eases the strain upon the yarn or thread being spun or twisted and reduces breakage. For instance, in spinning or twisting with a rotating flier or ring, such as have been referred to, and a receiver for yarn or thread rotated by the pull of the yarn or thread it is found that as the lower portion of the receiver becomes filled with yarn and the winding on approaches the upper end thereof there is an increasing tendency to breakage of the yarn or thread. This is due to the fact that the transverse strain of the yarn extending through the guide-eye of the rotating fiier or ring to the receiver acts with lOO IIO

gradually-increasing*leverage upon the blade of the spindle by which the receiver is constituted or upon which it is mounted, and consequently with correspondingly-increased tendency to occasion binding of the lower end of the spindle within the bearing or bear-V ings therefor. This produces a gradually-increasing resistance to the rotation of the spindle under the pull of the yarn or thread. However, by mounting the sleeve upon the spindle, with capacity to turnv upon and independently of the latter when the resistance to the rotation of thespindle increases, the sleeve will remain free to rotate upon the spindle, and thereby the tendency to occasion breakage of the yarn or thread will be obviated.

My invention has been designed for general use in spinning and twisting yarns and threads and is especially valuable for fine numbers and highvspeeds.
